In a large skillet, combine butter and heavy cream, then allow the mixture to gently simmer over low heat for approximately 2 minutes.
Incorporate the garlic, Italian seasoning, salt, and pepper by whisking thoroughly for an additional minute to infuse the flavors.
Gradually whisk in the grated Parmesan until it fully melts, yielding a smooth and creamy consistency.
Serve the sauce promptly over hot pasta or as desired.
